Y.Application-Anti), leii'asemin-Nb;iii-1150 1 e claims. (or; es-'19s") Myinvention relates to apparatu for dyeing yarn in. package form,particularly to spindles for supporting packages duringthe dyeingprocess; and for its primary object to provide an improved spindle whichis capable of increasing the volume of dye liquor therethrough andv thusenable more uni-ts to be dyedper spindle.

Ithas been the practice heretofore, as far as applicant is-awa1'e,-toprovide a perforatedv hollow spindle having. an open. socket atone endfor attachment-to a perforatedcylinder of a dye carrier and at. theother end a cap for sealing the liquor, so that flow thereofis-directedlongitudlnally along the open socket and spindle,

thence transversely throughthe perforationsof the spindle and tube onwhich the cap is wound, andfinally through the wound yarn; It has beenknown also to provide a fin type spindle, cross shaped in transversesection as indicated in Drum et al. Patent 2,306,719 of December 29,1942; for supporting packages during the dyeing process. However, inthese conventional spindles the volume of liquor, flow therethrough isrestricted to the internal open area of the spindles.

ln-the hollow perforatedspindle-the total available areais limited bythe internal. diameter therefoi' and, since the perforatedtubes'carry-ing the packages;- are superposed thereupon, thethickness-oi the perioratedspindle is the limiting factor; In-the fintype spindle the thicknessoi the material comprising the crossshaped'fins limits-v the areaavailable for liquor, flow.

Accordingly;.-it-is another object ofmy invention.,=to- -overcome theabovedisadvantages by providing-i a-greater area for liquor flow inthesupporting spindleand alsoat the socket end of the spindle;

Wit-h theabove objects. inview; an; embodiment of my: inventiondiscloses aspindle; assembly comincreasing, thevolume-gidiquonthatmayi-be-introduced into'the spindle.

For a more complete" understandingoi the nat'ureand s'cop'e of myinvention, reference may be had to the following detailed descriptionta'ken in conjunction with the accompanying drawing in which: n v

Fig. 2' is a sectional View of the sametakein along line 2-2 of Fi 1- inthe direction of the arrows; and- Fig. 3 is-another' sectionalviewtaken. along line 33 of Fig. 1 in-the-direction of the arrowsReferring now to the drawing; particularly to Fig. -1, there is showna'spin'dle assembly ID comprising an elongatedrsrod: H and asocke't l2111emovably attached: to a dye carrier plate It, which latter is ofconventional configuration and well known in the dye art.

The outer peripheral surface l4-of. the socket i2 is threaded'for' meshengagement with .a threaded opening l6 in the carrier plate [3 "and .Iprefer tormake this peripheral surfaceslightly tapered, asshown, so thatthe end portion: l1 thereof may be readily passed through and thusextend beyondthe plate :3 for apurpose that will appear hereinafter. Thesocket-end. portion H is shown provided" with a threaded,longitudinal'bore I 8 for mesh engagement with theithreaded" end" 19 ofthe rod H; which also includes a shoulder 21 'for limiting the depth towhich the rodmaybe inserted'sinto the socket. It isto be noted,therefore, that the end portion of the sccket acts as a closure when therodis assembled thereto. Inwardlyof this closure is formed" alongitudinafbore 212; the diameter of which is at least equal tothe"inner diameter of a; conp des a ou d. he fii ihe j .si rie .42. and"extend" ldngitudinany a" predetfniinedhistanc.

The total entrance cross-sectional area, as represented by the sum ofthe individual openings 26, is arranged to be greater than the crosssectional area of the bore 22 or tube 23 minus the cross sectional areaof the rod 1 l in order to provide, a mentioned hereinbefore, forincreased liquor flow therethrough.

This increased liquor flow will be readily ap parent from the followingmathematical comparison between a conventional spindle assembly having aperforated tubular spindle and the spindle of my invention. Aconventional perforated rayon cake tube, such as tube 23 in the drawing,has an inner diameter of In my spindle the spindle rod H is A" indiameter, which is sufficiently strong to support the required number ofwound packages 24. In the prior art perforated spindle tube the innerdiameter thereof is and it is to b noted that in conventional practicethe inner end of this tube is open and the dye liquor enters throughthis opening and, since the other opening is closed, the liquor isforced through the perforated openings in both tubes and thence throughth wound package, as is well known.

The areas of the various parts are as follows:

1. 0.40574 sq. in. for perforated tube 23 2. 0.04909 sq. in. for A"spindle rod H 3. 0.19635 sq. in. for perforated spindle of prior art Thedifference,

0.405740.04909=0.35665 sq. in.

represents the net cross-sectional area available for liquid flow in myarrangement; and, since the total cross-sectional area for liquor how inthe prior art spindle is 0.19635 sq. in., the difference,0.356650.19635=0.16030 sq. in;, represents the greater amount ofcross-sectional area available for liquor flow, which area is almostdouble that heretofore possible.

In view of the increased volume of liquor fiow available through thesocket of my invention it is thus possible to install more than theconventional three packages and still maintain a satisfactory flowcondition.

At the other or front end of the socket I2 is shown an enlargement 2?having a plurality of angularly disposed, side faces 28 in the form of ahexagon for facilitating, by use of a suitable tool, attachment of thesocket to the carrier plate. The enlargement 21' is also provided at itsfront face 29 with a recess St, the wall of which is arcuat in outlineand which begins at the front face 29 and continues rearwardly andinwardly, as shown, to the bore 22. The recess 3! is thus particularlyadapted to seat the perforated tube 23 coaxially with respect to thespindle rod II, as shown in Fig. 3, whether the spindle is mountedvertically or horizontally.

The assembly of the spindle to the carrier plate (3 is a simple andstraightforward operation requiring merely the rotational movement ofthe socket 12 until it is firmly secured in the threaded opening l6, asshown in Fig. 1, after which the elongated rod H is inserted into thethreaded opening !8 of the socket it. Once the spindle is in positionthe perforated tubes 23 carrying the packages 24 are mounted thereonwith the innermost tube 23 centrally disposed in the recess 3|.

To assure a coaxial arrangement of all superposed tubes I provide aspacer 32, having a recess 33, similar to recess 3|, on opposing facesthereof, between each pair of tubes 23 and also a similar self-centeringrecess on a threaded cap 4 34 for sealing, and a nut 36 securing theentire assembly together on the spindle rod ll.

From the foregoing description, it will be seen that my inventionprovides a simple, practical spindle which is formed of parts that canbe economically manufactured, easily handled, and can be convenientlyused. Further, with my invention it is now possible to substantiallyincrease the flow of dye liquor and thereby process more packages in thesame period. Also, repair of a bent spindle is readily eifectecl by merereplacement of the spindle rod l I.

As various changes may be made in the form, construction and arrangementof the parts herein, without departing from the spirit and scope of theinvention and without sacrificing any of its advantages, it is to beunderstood that all matters are to be interpreted as illustrative andnot in any limiting sense.
